Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a multi-functional four-wheel drive seeder. Background Technology

[0002] In agricultural production, sowing is a crucial step. However, traditional seeders are single-function machines, requiring workers to transport seeds and fertilizers separately, and also to perform fertilization after sowing. This increases operating costs and labor intensity, while reducing efficiency. Therefore, a multi-functional seeder is needed to improve the efficiency of crop cultivation.

[0003] In the prior art, utility model patent CN200420031531.9 discloses a vehicle-mounted multi-functional combined seeder. It features a high-position fertilizer applicator mounted on the rear of a rubber-tired tractor, with 1-6 fertilizer funnels at its bottom. A drive shaft runs horizontally through each funnel. The end of the drive shaft has a tightly fitted gear connected to a gear on the tractor's rear axle via a chain. The fertilizer applicator is connected to a furrow opener via the fertilizer funnels and a fertilizer delivery pipe. The gear on the drive shaft is connected to the seed wheel on the seeder via a chain. A connecting frame at the bottom of the seeder pulls a soil-supporting shovel. A tractor at the rear of the tractor pulls a trailer carrying a water tank via a tow bar, with the water tank's outlet pipe connected to the fertilizer delivery pipe along the tow bar. The gear on the tractor's rear axle is engaged with a clutch lever. This vehicle-mounted multi-functional combined seeder allows for multiple uses and single-person operation, integrating sowing, fertilization, and watering into a single process, thus improving labor productivity.

[0004] The aforementioned patent describes a multi-functional seeder equipped with a high-position fertilizer applicator, allowing fertilization to be completed during the sowing process. By combining sowing and fertilization in one step, it effectively improves crop planting efficiency. While this seeder integrates sowing and fertilization, significantly increasing work efficiency, the amount of seeds and fertilizer it can store is limited. When refills are needed, workers must transport the seeds and fertilizer to the seeder location, increasing their workload, wasting time, and reducing overall efficiency. Utility Model Content
